表型可塑性使动物能够灵活地调整自己的行为以适应社会环境——有时是通过表达几代人都没有表现出的适应性特征。我们通过实验进化来记录与父母照顾的供给和需求相关的社会特征的丧失，研究了当社会适应不经常表达时，社会适应可以有效地持续多久。我们让埋葬甲虫 Nicrophorus vespilloides 种群在实验室中在两种不同的社会环境中进化了 48 代。在“全面照顾”群体中，与父母照顾的供给和需求相关的特征在每一代都会表达，而在“无照顾”群体中，我们通过实验阻止这些特征的表达。然后，我们通过允许父母提供孵化后护理来恢复第 24、43 和 48 代无护理种群中的性状表达，并将这些社会特征与全面护理种群所表达的社会特征进行比较。我们发现，在无护理人群中，后代对护理的需求和男性提供的护理比女性提供的护理更快消失。我们认为，这反映了后代（雄性和雌性）替代性状表达选择强度的差异，这可以在孵化后护理中断时增强适应性。
Phenotypic plasticity enables animals to adjust their behavior flexibly to their social environment—sometimes through the expression of adaptive traits that have not been exhibited for several generations. We investigated how long social adaptations can usefully persist when they are not routinely expressed, by using experimental evolution to document the loss of social traits associated with the supply and demand of parental care. We allowed populations of burying beetles Nicrophorus vespilloides to evolve in two different social environments for 48 generations in the lab. In “Full Care” populations, traits associated with the supply and demand of parental care were expressed at every generation, whereas in “No Care” populations we prevented expression of these traits experimentally. We then revived trait expression in the No Care populations at generations 24, 43, and 48 by allowing parents to supply post-hatching care and compared these social traits with those expressed by the Full Care populations. We found that offspring demands for care and male provision of care in the No Care populations were lost sooner than female provision of care. We suggest that this reflects differences in the strength of selection for the expression of alternative traits in offspring, males and females, which can enhance fitness when post-hatching care is disrupted.
